Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas heating technology, and in particular to a wall-mounted gas heater. Background Technology
[0002] Traditional wall-mounted gas heaters generate heat by burning natural gas in the combustion chamber. This heat diffuses through the metal casing into the room, gradually raising the temperature and achieving the desired heating effect. However, indoor air circulation is limited, resulting in slow heat transfer. Furthermore, more heat dissipates outdoors through the exhaust duct, increasing energy consumption and potentially causing heat buildup and other safety issues. In addition, traditional gas heaters typically use mechanical ignition devices. These require specialized structures, with different sizes of mechanical structures needed for different heater sizes, placing higher demands on design, production, and testing. Users also need to learn how to use these mechanical devices, requiring them to confirm the gas valve is open and coordinate hand and eye movements for successful ignition. Generally, gas heaters offer multiple adjustable settings, but these settings require users to learn when to use which setting, hindering ease of use. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a wall-mounted gas heater that is simple and safe to use, highly efficient in heating, and energy-saving. It can solve the problems of traditional gas heaters, such as the need for a certain learning cost in use, the lack of a complete safety system, and low energy utilization.
[0004] The technical solution adopted by this utility model is as follows: This utility model includes a shell, the interior of which is divided into a combustion zone and a control zone by a partition. In the combustion zone, an exhaust core, a heat exchanger air chamber, a combustion core, and a fan are arranged sequentially from top to bottom. Several heat outlets are also provided on the front of the shell corresponding to the position of the heat exchanger air chamber. A control system connected to the combustion core and the fan by a control line is provided in the control zone. The bottom of the control system is connected to the external gas supply. A control display electrically connected to the control system is provided on the shell at a position corresponding to the control zone. It also includes an intake and exhaust pipe connected to the back of the shell. The intake and exhaust pipe is divided into an upper exhaust port and a lower intake port by a second partition. The upper exhaust port is connected to the exhaust core, and the lower intake port is connected to the combustion zone. The bottom of the shell has a hollow design, and the fan intake port is located at the hollow position, while the exhaust port is aligned with the combustion core.
[0005] Furthermore, the combustion core includes an ignition panel, a burner, a gas pipeline, and a combustion chamber. The combustion chamber is a cuboid welded from four electro-galvanized plates. The burner is fixedly installed in the lower part of the combustion chamber. The gas pipeline is connected to the burner and its corresponding control system. The ignition panel consists of an ignition needle, a flameout protection device, and an ion sensing needle. It is fixedly installed in the combustion chamber above the burner. The ignition panel is connected to the control system. The top of the combustion chamber has an opening corresponding to the air chamber of the heat exchanger, and the bottom extends downwards with an air guide space corresponding to the fan.
[0006] Furthermore, a third partition is provided between the combustion zone and the inner wall of the housing, forming an air guide duct between the third partition and the inner wall of the housing. The top of the air guide duct is connected to the lower air inlet. The exhaust core, the heat exchanger air chamber, the combustion chamber, and the fan are fixedly installed on the side of the third partition located in the combustion zone. An air inlet notch is provided on the air guide interval, which is connected to the bottom of the air guide duct.
[0007] Furthermore, the control system includes a control motherboard and a temperature sensor, a carbon monoxide detection sensor, and a gas sensor, all electrically connected to the control motherboard. The control motherboard uses a microprocessor chip and is electrically connected to the fan, the control display, and the flameout protection device. The flameout protection device includes a thermocouple and a solenoid valve that are electrically connected to each other. One end of the solenoid valve is connected to the burner through the gas pipeline, and the other end is connected to external gas.
[0008] Furthermore, the air chamber of the heat exchanger adopts a finned heat exchanger, the heat exchange tube is made of copper and is set in the vertical direction, the fin direction is perpendicular to the outer side of the heat exchange tube, the upper and lower ends of the heat exchange tube protrude from the fin area and extend into the exhaust core and the combustion core respectively.
[0009] Finally, the exhaust core is a hollow cuboid with an opening at the bottom corresponding to the air chamber of the heat exchanger, an exhaust outlet on the top back that communicates with the upper exhaust port, and several heat dissipation outlets at the top of the housing corresponding to the exhaust core.
[0010] Compared with existing technologies, the beneficial effects of this invention are as follows: By subdividing the internal area of the housing, this invention, in addition to continuously supplying air to the combustion core using natural wind through the traditional air inlet, also provides additional air to the combustion core through the fan located at the bottom of the housing. This also provides power for the diffusion of heat after combustion, allowing heat to diffuse more quickly from the heat exchanger air chamber through the heat outlet to the indoor environment, improving the heat exchange efficiency and heating effect of the device. The control display integrates functions including a power switch, start button, mode switching button, setting button, and temperature control button. The system is protected and precisely temperature-controlled through the flameout protection device, the fan, the temperature sensor, the carbon monoxide detection sensor, and the gas sensor, simplifying the user's learning curve and improving the safety of the device. Therefore, this invention is simple and safe to use, highly efficient in heating, and energy-saving, solving the problems of traditional gas heaters requiring a certain learning curve, lacking a comprehensive safety system, and having low energy utilization.

[0016] like Figures 1 to 5As shown, this utility model includes a housing 1. The interior of the housing 1 is divided into a combustion zone 3 and a control zone 4 by a partition 2. In the combustion zone 3, an exhaust core 5, a heat exchanger air chamber, a combustion core, and a fan 6 are arranged sequentially from top to bottom. Several heat outlets 7 are also provided on the front of the housing 1 at positions corresponding to the heat exchanger air chamber. A control system 8 is provided inside the control zone 4 and is connected to the combustion core and the fan 6 by control lines. The bottom of the control system 8 is connected to the external gas supply. A control display 9, which is electrically connected to the control system 8, is provided on the housing 1 at a position corresponding to the control zone 4. The model also includes an intake and exhaust pipe 10 connected to the back of the housing 1. The intake and exhaust pipe 10 is divided into an upper exhaust port 12 and a lower air inlet 13 by a second partition 11. The upper exhaust port 12 is connected to the exhaust core 5, and the lower air inlet 13 is connected to the combustion zone 3. The bottom of the housing 1 is hollowed out, and the air inlet of the fan 6 is located at the hollowed-out position, while the air outlet is aligned with the combustion core. Several heat outlets 7 adopt a strip design and are arrayed on the front of the housing 1, connected to the air chamber of the heat exchanger to ensure heat exchange efficiency; the controller display 9 records various parameters of the heater in real time during operation, including operating mode, temperature, and alarm information; the control display 9 integrates functions such as power switch, start button, mode switching button, setting button, and temperature control button, which can adjust the operating parameters of the heater.
[0017] In this invention, the bottom of the housing 1 is hollowed out to provide space for the gas inlet device and heat exchange. The back is an integrated air intake and exhaust channel 10. This integrated structure design makes better use of space and saves manufacturing costs. The left, right, and top sides of the housing 1 contain holes for a wall-mounted mounting plate. The mounting plate must first be fixed to the desired installation position of the heater through the pre-drilled holes, and then the holes on the heater housing are aligned with the holes on the mounting plate and secured with screws. In this invention, the fan 6 is a high-efficiency and energy-saving device that can withstand long-term use in a certain temperature environment. The fan 6 is fixed under the combustion core inside the housing 1 by the mounting plate. The fan 6 must be firmly fixed to ensure safe use. The size of the selected fan 6 corresponds to the combustion core, that is, the size of the fan 6's air outlet is the same as the width of the combustion core, and the position of the air outlet must be aligned with the air duct of the combustion core to ensure that all the air generated by the fan 6 can be delivered into the air duct.
[0018] The combustion core includes an ignition panel 14, a burner 15, a gas pipeline, and a combustion chamber 16. The combustion chamber 16 is a cuboid welded from four electro-galvanized plates. The burner 15 is fixedly installed inside the combustion chamber 16 at a lower position. The gas pipeline is connected to the burner 15 and the corresponding control system 8. The ignition panel 14 consists of an ignition needle, a flameout protection device, and an ion sensing needle. It is fixedly installed inside the combustion chamber 16 above the burner 15. The ignition panel 14 is controlled and connected to the control system 8. The top of the combustion chamber 16 has an opening corresponding to the air chamber of the heat exchanger, and the bottom extends downward with an air guide spacer 17 corresponding to the fan 6. A third partition 18 is provided between the combustion zone 3 and the inner wall of the housing 1. A duct 19 is formed between the third partition 18 and the inner wall of the housing 1. The top of the duct 19 is connected to the lower air inlet 13. The exhaust core 5, the heat exchanger air chamber, the combustion chamber 16, and the fan 6 are fixedly mounted on the side of the third partition 18 located in the combustion zone 3. An air inlet notch 20 connected to the bottom of the duct 19 is provided on the air guide partition 17. During operation, external natural air enters the combustion core through the lower air inlet 13 and the perforation at the bottom of the housing 1, ensuring normal combustion. The heat generated by combustion diffuses outward through the heat exchanger air chamber, while the fan 6 provides power for heat diffusion, allowing heat to diffuse more quickly from the heat exchanger air chamber into the indoor environment.
[0019] The control system 8 includes a control motherboard and a temperature sensor, a carbon monoxide detection sensor, and a gas sensor, all electrically connected to the control motherboard. The control motherboard uses a microprocessor chip and is electrically connected to the fan 6, the control display 9, and the flameout protection device. The flameout protection device includes a thermocouple and a solenoid valve that are electrically connected to each other. One end of the solenoid valve is connected to the burner 15 through the gas pipeline, and the other end is connected to external gas. When the gas stove flame is accidentally extinguished, the potential generated by the thermocouple disappears, and the solenoid valve automatically closes under the action of its own spring, blocking the gas valve inlet and ensuring gas safety. When the temperature sensor detects that the temperature reaches or exceeds the preset safety limit, the overheat protection device will automatically cut off the gas inlet or increase the fan speed to prevent the temperature from rising further. When the gas supply and oxygen supply are constant, the flame combustion temperature is also constant. Utilizing this principle, when the control system detects that the temperature fed back by the thermocouple is lower than the set temperature, the solenoid valve will automatically close. The carbon monoxide detection sensor will monitor the carbon monoxide concentration in real time. If it exceeds the safety value or the set value, the solenoid valve will close and provide an alarm to prompt the user to ventilate. The gas sensor will monitor the gas concentration inside the heater in real time. If the gas concentration exceeds the safety value or the set value, the solenoid valve will close and display an alarm message on the display screen to prompt the user to check the pipeline.
[0020] The air chamber of the heat exchanger adopts a finned 22-type heat exchanger, which effectively improves the heat diffusion efficiency. The heat exchange tube 21 is made of copper, which effectively improves the thermal conductivity while also taking into account economy. It is set in the vertical direction, with the fins 22 set perpendicular to the outer side of the heat exchange tube 21. The upper and lower ends of the heat exchange tube 21 protrude from the finned 22 area and extend into the exhaust core 5 and the combustion core, respectively.
[0021] The exhaust core 5 is a hollow cuboid with an opening at the bottom corresponding to the air chamber of the heat exchanger, and an exhaust outlet 23 on the top back that communicates with the upper exhaust port 12. Several heat dissipation outlets 24 are also provided on the top of the housing 1 at positions corresponding to the exhaust core 5. These heat dissipation outlets 24 are arranged in a strip array on the top of the housing 1, serving to assist in heat conduction into the room while effectively preventing heat accumulation inside the device. When the combustion gas inside the core burns, the housing 1 transfers heat outwards. Failure to dissipate this heat in a timely manner will affect the heater's performance. The heat dissipation outlets 24 provide a channel for this heat dissipation, thus providing heat into the room, improving energy efficiency, and eliminating factors that could affect the heater's performance, ensuring safe operation.
[0022] When this utility model is in operation, the control display 9 will show the real-time operating status, including the set temperature, real-time temperature, fan airflow, and real-time alarms. During normal operation, the system will first compare the current temperature with the set temperature. The system will continue to operate only if the current ambient temperature is lower than the set temperature. After reaching the set temperature, the system will automatically adjust the opening of the solenoid valve to ensure reasonable energy consumption and maintain a balanced room temperature.
[0023] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
